How secure are web-based email services?
Most web-based email services transmit messages as clear (unencrypted) text. Unencrypted web-based email may be vulnerable to illicit attempts to intercept email communications. You can check with your email service provider to learn about your specific email service and its encryption or security features, if any. Typically, only the login page is SSL encrypted, and the closed padlock (or key) icon will be displayed on your web browser for any such pages. Please note that T-Mobile does not provide security with respect to your use of third party websites or services, such as web-based email. If you choose to use web-based email on our service, we strongly recommend that you avoid using it to transmit information you deem confidential, and if possible, that you encrypt any attachments before sending them.
